[SWIFT]로그 예쁘게 찍기

개발하면서 로그찍을 일이 많아 로그종류 / 시간 / 파일경로 / 클래스 / 함수명 / 라인수 / 복수의 데이터가 표시되게 만들어봤습니다. 

글로벌로 선언해서 사용하면 됩니다.

enum eDirection: Int {
    case UI,SEND,RECEIVE,WEBVIEW,SCHEME,OBSERVER,PUSH,ETC,ERROR
}

func log<T>(direction: eDirection,
                        ofType value: T,
                        file: String = #file,
                        function: String = #function,
                        line: Int = #line,
                    datas: Any?...){
       
    
    #if DEBUG
    let now = Date()
    let formatter = DateFormatter()
    formatter.locale = Locale(identifier:"ko_KR")
    formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
    formatter.timeZone = TimeZone(abbreviation: "KST")
    let time = formatter.string(from: now)
    
    print("\n===============================================================================\n")
    switch direction {
    case .UI:
        print("💚💚💚[ \(direction) LOG : \(String(describing: time)) ]💚💚💚")
    case .SEND:
        print("🔺🔺🔺[ \(direction) LOG : \(String(describing: time)) ]🔺🔺🔺")
    case .RECEIVE:
        print("🔻🔻🔻[ \(direction) LOG : \(String(describing: time)) ]🔻🔻🔻")
    case .WEBVIEW:
        print("💜💜💜[ \(direction) LOG : \(String(describing: time)) ]💜💜💜")
    case .SCHEME:
        print("⚡️⚡️⚡️[ \(direction) LOG : \(String(describing: time)) ]⚡️⚡️⚡️")
    case .OBSERVER:
        print("📩📩📩[ \(direction) LOG : \(String(describing: time)) ]📩📩📩")
    case .PUSH:
        print("📬📬📬[ \(direction) LOG : \(String(describing: time)) ]📬📬📬")
    case .ETC:
        print("💛💛💛[ \(direction) LOG : \(String(describing: time)) ]💛💛💛")
    case .ERROR:
        print("☠️☠️☠️[ \(direction) LOG : \(String(describing: time)) ]☠️☠️☠️")
    }
    
    print("Log File : \(file)")
    print("\n[Log ClassName] \(type(of: value as Any))")
    print("[Log Function ( \(line) Line )] \(function)")
    
    if datas[0] != nil {
        var index = 1
        print("\n[Log Data]")
        for data in datas {
            print("Data Value[\(index)] : \(String(describing: data ?? "NULL"))")
            index += 1
        }
    }
    
    print("\n===============================================================================")
    #endif
}

            "앱버전 : \(String(describing: appVersion()!))",
            "UUID : \(String(describing: UIDevice.deviceUUID!))",
            "NSUUID : \(String(describing: UIDevice.deviceNSUUID))",
